Xamarin Android: Create Android TextInputLayout And Spinner

Let’s start,

Step 1: Open Visual Studio->New Project->Templates->Visual C#->Android->Blank app

Select blank app. Give the Project Name and Project Location.

Step 2: Go to Solution Explorer-> Project Name-> Components, right click to get more components, open new dialog box. This dialog box is required to search the design, add the Android Support Design Library Packages.

Step 3: Next to Add Theme.AppCompat.Light.NoActionBar, create styles.xml file. Go to Solution Explorer-> Project Name->Resources->values, right click to Add-> New Item, open new dialog box. Select XML file and give the name for styles.xml,



Step 4: Create colors.xml file. Go to Solution Explorer-> Project Name->Resources->values, right click to Add-> New Item, open new dialog box. Select XML file, give the name for colors.xml.



Step 5: Open Solution Explorer-> Project Name->Resources->values->colors.xml. Click to open Design View and the code, given below:

<?xml version="1.0" encoding="utf-8" ?>
<resources>
    <color name="window_background">#8AA5B9</color>
</resources>

Step 6: Open Solution Explorer-> Project Name->Resources->values->styles.xml. Click to open Design View and the code, given below:

<?xml version="1.0" encoding="utf-8" ?>
<resources>
    <style name="Theme.DesignDemo" parent="Base.Theme.DesignDemo">

    </style>
    <style name="Base.Theme.DesignDemo" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">#2196F3</item> <item name="colorPrimaryDark">#1976D2</item> <item name="android:windowBackground">@color/window_background</item>
    </style>
</resources>

Step 7: Open Solution Explorer-> Project Name->Resources->values->Strings.xml. Click to open Design View and the code, given below:

<string name="pro_Languages1">Type of Languages</string>
<string-array name="pro_Languages">
    <item>C#</item>
    <item>.Net</item>
    <item>Java</item>
    <item>C</item>
    <item>C++</item>
    <item>Swift</item>
</string-array>
</resources>

Step 8: Open Solution Explorer-> Project Name->Resources->layout ->Main.axml. Click to open Design View and the code, given below:

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent">
    <LinearLayout android:orientation="vertical" android:layout_marginTop="80dp" android:layout_width="match_parent" android:layout_height="wrap_content">
        <android.support.design.widget.TextInputLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/textuernameInputLayout">
            <EditText android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/txtusername" android:hint="User Name" android:singleLine="true" /> </android.support.design.widget.TextInputLayout>
        <android.support.design.widget.TextInputLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/textpasswordInputLayout">
            <EditText android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/txtpassword" android:inputType="textPassword" android:hint="Password" android:singleLine="true" /> </android.support.design.widget.TextInputLayout>
        <Spinner android:id="@+id/ddlmechservicetype" android:layout_width="fill_parent" android:layout_height="wrap_content" />
        <Button android:text="Click" android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/btnclick" /> </LinearLayout>
</LinearLayout>

Step 9: After Design view creation open Solution Explorer-> Project Name->MainActivity.cs then following below steps.

Step 10: Add below Namespaces,

using Android.Support.V7.App;
using Android.Support.Design.Widget;

Step 11: Create Spinner and TextInputLayout variable, declare the Spinner and TextInputLayout within the OnCreate().before to change to the Activity to AppCompatActivity.

//TextInputLayout
TextInputLayout txtlayoutusername = FindViewById < TextInputLayout > (Resource.Id.textuernameInputLayout);
TextInputLayout textpasswordInputLayout = FindViewById < TextInputLayout > (Resource.Id.textpasswordInputLayout);
EditText txtusername = FindViewById < EditText > (Resource.Id.txtusername);
EditText txtpassword = FindViewById < EditText > (Resource.Id.txtpassword);
Button btnclick = FindViewById < Button > (Resource.Id.btnclick);
//Spinner
spinner = FindViewById < Spinner > (Resource.Id.ddlmechservicetype);
var adapter = ArrayAdapter.CreateFromResource(this, Resource.Array.pro_Languages, Android.Resource.Layout.SimpleSpinnerItem); //Assign Array List Strings
adapter.SetDropDownViewResource(Android.Resource.Layout.SimpleSpinnerDropDownItem);
spinner.Adapter = adapter;
//Button Click
btnclick.Click += (sender, e) =>
{
    //Showing Notifications
    Toast.MakeText(this, txtusername.Text, ToastLength.Short).Show();
    Toast.MakeText(this, txtpassword.Text, ToastLength.Short).Show();
    Toast.MakeText(this, spinner.SelectedItemPosition.ToString(), ToastLength.Short).Show();
};

Step 12: Press F5 or build and run the Application. 

Finally, we successfully created Xamarin Android TextInputLayout and Spinner app.
